  • The resource of the timing chain and phase shifter sometimes does not even reach 100 thousand kilometers;
  • The turbine can quickly fail due to coking of oil in its supply pipes;
  • The fuel pressure sensor in the high pressure fuel pump often leaks, which is simply fraught with fire;
  • The engine is prone to oil consumption, if you miss the oil level, it will turn the liners.
